Zyphra is a San Francisco full stack AGI company building open-source foundation models across language, speech and brain-computer interfaces.
Zyphra is a full stack AGI company based in San Francisco that develops foundation models across multiple modalities, with the stated aim of building complete infrastructure for open-source superintelligence. Its work spans large language models and frontier reasoning, text-to-speech and audio generation, brain-computer interfaces and neural signal processing, computer vision, and general-purpose AI agents. The company combines research with engineering work on inference efficiency, novel neural architectures, hardware-optimized performance, and optimization across accelerators from AMD and NVIDIA as well as the cloud.
Three named model families anchor the product line. ZAYA covers frontier reasoning language models; ZONOS is an expressive text-to-speech foundation model; and ZUNA is a foundation model aimed at brain-computer interface applications. The company releases advanced AI capabilities as open models and positions human alignment and safety as central to its research methodology.
Zyphra works with major technology companies including IBM and AMD. For a marketing engineer, the relevant surface is a technical, open-source-facing product portfolio spanning speech, language and neurotechnology, with a research narrative grounded in published models and cross-hardware performance work.
